Gas Pedal Delay

i have done tb bypass's,muffler delete,intakes and grounds and all this helped alot.now, in the mornings the ambient temp is down in the low 60's and when i take it to 5k rpms in a couple of gears and then put it in 6th,mashed the pedal at 80mph,car accelerates like im driving a moped and oil temp is barely over 180.is it possible i have partially clogged cats or is this the symptoms everyone has ?

im really trying to like this car but i hate driving a car that acts like something is wrong with it 90% of the time unless im getting on the interstate hence the main reason i started moddin the car to try and keep the engine bay as cool as i can.i stay on top of oil maintenance and make sure my maf's and map sensor are clean.thermostat seems to be operating normally and coolant is where its supposed to be in the overflow.

in other words,i have to drive this car like grandpa around town shifting at say 3.5k or i get bogging like something is wrong with the car.doesnt matter what gear im in. i see other people on here tracking and drifting their car with no problems but as soon as i take it say from 0-130 and immediately slow down in 80 ambient,coolant is REALLY hot(too hot imo). and by that time the oil is 200 from the beginning run of 180 oil temp, its bog city like i just lost 100 hp or more.imo,something is causing the coolant to get too hot and the radiator cant keep up.what am i doing wrong ? or is it i have a sports car that i cant drive like a sports car ?.im seriously at a loss here and i have no cel's.

i have read on here that a cbe helps with this ? right now my main concern is to try and fix this problem before i do any more power modding.if i cant,car will have to go.i have also checked the brake switch and its operating normal as well. any insight before i get rid of the car ? and btw,these symptoms were way worse when the car was completely stock.

i have also read there was a guy on here that his tuner turned something off in the ecu and he claimed to never bog again.i would die for that info right now.WHAT DID HIS TUNER DISABLE ?

EDIT; nvmd.started lookin for another car after 4k miles
